Works really well!
Brought this to check any live wires before doing some rewiring to be safe and so far so good! Good quality, instructions are very clear and it’s a bonus to have the sound along with it.

Good
I bought it as a spare. I had two £20 testers and one stopped working. It is good for the price but not as robust as my Fluke tester

Low settings make it very sensitive to volts.
I am impressed. It works.

More than just a voltage tester - its a full multimeter
I bought this unit as I was replacing the faceplate on a socket in my house. I wanted to be sure that there was no voltage running through the wires (even though the master fuse was off and cut power to the whole house). When researching testers, I had heard mixed reviews about non-contact testers. Some people seem to think they are not reliable enough, but I found this tester to tick pretty much every box in my experience: 1) It has an bright LED screen showing you that the tester is on, so you can ensure that you haven't run out of battery 2) The display gives you a visual gauge of how strong the detection is, as well as emitting a sound and flashing to indicate when current is detected 3) It was sensitive enough to detect live wires behind my plasterboard in NCU mode 4) It also comes with probes which lets it act as a full multimeter to test DC Voltage, AC Voltage, Resistance, Continuity, Frequency, Capacitance, and Diode measurement, as well as Live Wire and Non-Contact phase sequence detection It does take a few seconds to start up, and can take a little bit of time to detect the voltage, but all in all it does what I need and will be super useful for other DIY and electronics projects.

Safe and simple to use.
Easy to read and a high accuracy of detection. With a built in torch to assist in dark areas during power outages. The unit comes with clear instructions and the build quality is excellent. A great tool that could save you from a nasty shock.

A really good buy
I’m having some work done on the house and wanted to check what cabling is defunct and can be removed. This is an excellent piece of kit. It’s easy to use and clearly detects current.
